Referring now to the drawings in detail, in Fig. 1 there is shown a lipstick dispenser casing orholder indicated generally at 10. The casing or holder comprises an inner operating guide sleeve 12, which is provided-With anelongated slot 13, parallel to the longitudinal axis of the casing or holder, and which is formed at its bottom end outer shell, parts bewith and enlarged operating head or knob 14 having a der 17xat its top end. Above the operating knob 14, the

sleeve 12 is surrounded by a spiral tubular member 18 formed with a spiral slot 18 extending from one end thereof to the other end thereof, the upper end-ofthe tubular member being located immediately below the shoulder17 onthesleeve 12. The tubular member18 in.turn:.is encased in an outer tubular shell:19,' the latter seating on'the shoulder 16 on the sleeve 12.

The shell 19 makes a fairly tight frictional contact withlthetubulari member 18Tso as to press the same in wardly toward the sleeve 12 while permitting freerotation of the member18fand shell 19 with respect to the sleevelZ: The shell 19 is provided at its upper end with air-inwardly extending flange'ZO to improve the appearance of thecasing or holder. The spiral tubular member 18 and the outer shell 19 are assembled in such a manner as to. preclude relative movement therebetween. The operating sleeve 12may be rotated within the spiral tubularmember'lS'by means of the operating knob 14.-

A: cap or cover 21 is provided to cover the casing, this capwbeing adapted to frictionally engage the side portion' of the operating sleeve 12 below the shoulder 16 so as .to'sbeieasily; removable: therefrom. If desired the outer surface of the cap may be knurled.

Mountedfor movement along a predetermined axis within :the inner operating sleeve l2 is a' cylindrical cam follower or supporting'member 22. The cam follower is cup-shaped having a flat bottom wall 23 formed with a central opening 24'and iwithradial slots 25 extending from said opening to the outer peripheral edge of the bottom:.wall thereby enhancing the resiliency of the'bottom: wall. The centralopening 24 is formed with an outwardly extending tapered flange forming a locking ring 26. The side wall of the cam follower, midwayits height, is outstruck' forming a tubular camming lug-or pin .27, projecting. slightly outwardly therefrom. A series of annular arrangedholes 28 is formed in the bottom wall 23. adjacent its outer. periphery.

It will'thus be apparent that upon rotation of the operatingsleeve 12..with respect" to the spiral tubular member 18, the spiral tubular member remaining stationary with the she1l;19; .the cam follower will move in or out in the sleeve 12 due tozthe movement of the lug or pin 27in the spiral slot 18 in thespiral tubular member 18.

The above described construction is typical and standard of a well-known conventional form of lipstick dispenser casing or holder and is known as the swivel type or rotary lipstick casing or holder.

According to the present invention, I provide a cupshaped lipstick holding device or carrier 36 to be used with the above construction which is adapted to be readily snapped into and out of the cam follower 22 and which may be used interchangeably with any standard lipstick dispenser casing or holder. As shown in Fig. 6, this carrier comprises an elongated hollow cylindrical body 31 closed at one end by a flat wall 32 and being openat the other end. The body is enlarged or of larger diameter from a point midway its ends to the open end thereof thereby providing a shoulder 33 midway its ends. The enlarged portion of the body is formed with a series of'threads or corrugations 34 throughout its length, the-remainder of the body being smooth. The closure wall is formed with an outpr'essed protuberance or nipple-35 with a round outer end. A series of smaller protuberances or nipples 36 are pressed out of the bottom wall adjacent its outer periphery. The body is also formed with outwardly projecting spring fingers 37 spaced equidistantaround the smooth portion thereof and with opposed inwardly projecting nipples 38 adjacent its open end.

The carrier is adapted to carry a stick of material to begdispensed, suchas, for example, a lipstick 40. The lipstick is" forced through the body of the carrier to its seaton'the' bottom wall 32 thereof and is yieldingly held in position by the inner projections 38. A tubular cap or cover 41 with a conical-shaped closed end and with an open other end, preferably formed of suitable plastic material, is positioned over the lipstick 40 with its open end seated on the shoulder 42 formed by the uppermost corrugation 34. A band or tape 43 of plastic or the like may be placed around the joint between the top end of the carrier and the lipstick to hold the cap in place. This carrier with its lipstick and cap constitutes a'refill or replacement unit capable of being mounted in and used with any standard lipstick dispensing casing or holder.

In mounting the carrier in the cam follower, the central nipple 35 on the carrier is snapped through the central opening 24 in the cam follower, into interlocking relation with the flange or ring 26 thereof, the slitted bottom wall 23 of the cam follower permitting this snap action. At the same time, the protuberances 36 seat in the holes 28 in the bottom wall 23, and the carrier is held against displacement by the frictional engagement of the fingers 37 with the wall of the cam follower.

In using the improved holder, the cap 21 is removed from the casing and the members 12 and 18 turned with respect to each other so as to move the cam follower 22 and carrier 30 outwardly to the open end of the casing or holder in order to expose the lipstick 40 for use. After the lipstick has been used, the members 12 and 18 are rotated again with respect to each other to move the cam follower 22 to the bottom of sleeve 12 when the cover 21 is replaced.

If it is desiredto replace stick 40 by another stick or to replace a refill or replacement unit, the cam follower 22 and carrier 30 are again moved to the open end of the casing or holder, during which operation the corrugated portion of the carrier is moved to a position above the top of the casing thereby exposing a pry hole 44 formed in the carrier adjacent its top end. A tool (not shown) may be inserted through the hole and the carrier with its lipstick lifted out of the cam follower. A fresh lipstick or a complete refill unit including a lipstick may be readily inserted into the cam follower.

In the modification of the invention shown in Fig. 10, the dispenser casing or holder comprises a plastic tubular body 50 closed at one end and open at the other end. A tubular member 51 is inserted in the open end of the body 50 and has a shouldered portion 52 seated against the edge of the open end of the casing. The inner end of the tubular member 51 is closed with a flat bottom wall 53. A central opening 54 with an outwardly directed flange 55 is formed in the bottom wall. A series of holes 56 is formed in the wall 53 in annular formation around the central opening.

A carrier member 57 carrying a lipstick 58 is adapted to vbe inserted through the tubular member 51. The carrier is formed with a rounded central protuberance 59 on its bottom wall and with spaced depending pins 60 around the protuberance 59. When the carrier is forced to its seat on the bottom wall 53 of the tubular member 51 the central protuberance 59 snaps into interlocking relation with the flange 55 and the pins 60 seat in the holes 56. The carrier with its lipstick is thus releasably held in position. Spring fingers 61 formed on the side of the carrier, frictionally engaging the inner surface of the tubular member 51, also serve to hold the carrier against displacement on its seat. A plastic cap 62 is adapted to cover the lipstick and tubular member 51 when the carrier is seated. Flanged plates 63 and 64 of metal may be slipped over the closed ends of the casing 50 and cap 62, respectively, to reinforce such ends and to decorate the holder.

While I have illustrated and described the preferred embodiments of my invention, it is to be understood-that I do not limit myself to the precise constructions herein disclosed and that various changes and modifications may be made within the scope of the invention as defined in the appended claims.
